Magnesium in Lightweight Construction: Myths vs. Reality

BOLE Intelligent Machinery, we are certain that magnesium will be the material of the future in lightweight construction. Unfortunately, there are many preconceptions about this material, which certainly stem from our school days, when teachers would set magnesium powder on fire, and from a lot of misinformation spread by so-called experts.

We at BOLE Intelligent Machinery want to show you transparently what the real advantages and disadvantages of magnesium components are.

Here is a video on the flammability and combustibility of magnesium components:

You can see that, depending on the wall thickness of the component, the time it takes for the component to ignite varies with a  uniform heat input (of 1500°C).

The thicker the wall thickness, the more time it takes for the component to ignite. It is interesting to note that after ignition, no flame forms, contrary to what is usually described as bright and explosive. Furthermore, it can be seen that when the heat source is removed, the magnesium component does not continue to burn like a torch  until 100% of the material is consumed.

I think that with this analysis of the flammability and combustibility of magnesium components, we have been able to show that magnesium as a material for lightweight construction is not as dangerous as it is always described.

If you have any further questions on the subject of magnesium, we will be available to answer them at the  K-Messe trade fair from October 8 to 15, 2025, at the exhibition center in Düsseldorf.  There, we will be demonstrating our magnesium thixomolding technology on an MTX 300 and showing you, using components, what will be possible in the future with magnesium, including for your components.

Now you're probably wondering why the BOLE guys are going to a plastics trade fair with a metal technology.

It's relatively simple: we build very good plastic injection molding machines, but we are certain that magnesium, in combination with Thixomolding injection molding technology, will replace some plastic components in the future. Furthermore, we believe that in lightweight construction in the future, the much-discussed openness to technology will be important anyway.

We are convinced that there will not only be plastic or metal parts. We believe that metal/plastic hybrid components will certainly be the key.
